02 fbw engine, runs fine when cold and pulls well . When it is up to running temp the engine feels flat and down on power until turbo kicks in , this all started after filling up at supermarket but I have run a couple of tanks of fuel through it since . Don't know if was bad fuel or just a coincidence that this problem started then , it's a little better on garage fuel now . Also has a random hot start problem when it only starts when key is released from cranking engine

Had new belts and filters about 3000 miles ago
Fuel primer stays hard overnight
New fuel pickup in tank and replaced rotten fuel pipes at the back

Don't know where to look next so any help would be great

did they change the cam belt?
could be a tooth out on the timming marks

I did the belts on it and it's been fine until a couple of weeks ago, I did adjust the turbo to sort out the over boost it runs at 12psi on acceleration and settles to 10 psi normal driving

could have jumped a couple of teeth more noticable when hot

boost sounds fine to me

Quick strip down this weekend then , going to Norfolk in it next week

gotta be worth a look seen it happen before

someone else may have another idea

Lets ask the boss @Alan G

he has lots of experience with fuel pumps and stuff like that

Certainly could be the pump timing out a tooth. I dont think its a fault with the pump itself, best strip it & check the marks first.

old wise one has spoken

Got to use it for work but will strip it down at the weekend and see what's going on in there , thanks for the advise

have fun report back here will be interested in what ya find

Nothing serious I hope as the car is off the road waiting for me to do the brakes

brakes will be quicker!

Seized rear callipers on the car and I can't get all my camping gear in it

as a wise @skotl once said .......... have you changed the fuel filter ? I change mine every 5,000 miles regardless. It may have picked up some sh1te from the old stack pipes perhaps ?

if it were me I'd change the filter and fill it up with forte (the filter not the tank) and give that a go first
and also check the air filter isn't blocked too

Just get new calipers new discs n pads simples a hour each side done no more worries

I hang my head in shame for this one , got off work early so had a look around the truck for anything obvious that may cause running problem . It was when I looked at the fuel lines I replaced and discovered the loose fuel feed pipe on the stack . So half a tank of v power diesel and a quick turn of the screwdriver and all seems well , did find one glow plug not working so ordered new ones

glad you got it sorted bud , and the best fixes are the cheap fixes to all good eh ?

at least you didnt have to strip the whole thing down again

Also found fuel pipes under bonnet are perished and going hard

best get urself a roll of fuel line and a bag of fuel line clips

I used the last of the 6mm when I did the back of the truck , tried to blag some off my mate but garage had none
